Specification of Letters Patent No. 24.469. dated June 21. 1859.

To all whom it may concern:

lte it known that I. Annuirrrs Luucown.

of ('ohm'tou. Hlelthen county. h'tate of New York. have invented an lniirovenient in Self-Aeting Brakes for Sleigis: and I do hereby deelare that the following is a full and exact description of its eonstruetiou and operation. refereln-e heing had to the areolupanying drawings and to the letters of ret'ert'llt't marked thereon. so as to enable others skilled in the art to make and use my in- \etttiult.

Figure I. of the :u-eonipauying drawings represents a perspm-tive view of a sleigh )l'tl\ ided with my selt'aeting hrake. Fig. 2. is a side view of one of the brake eyes ll. and hrake U. the latter being repl'eset'lled in three ditl'erent positions In full black lines. in dotted hlaek lines. and in red. Fig. 23. represents one of the brake eyes.

The tongue E. of the sleigh is provided with a groove for the reeeption of the brake rod 1).

pin ll. projeeting from the front end of the brake rod passes through a rorre spondiug hole in the ferrule A. Wlllt'll fits hmsely over the end of the tongue E. The horses are hitehed to a hook t. projeetiug from the ferrule. The other end of the hrake rod is linked to a ronueetiug rod l. Wllltll latter serves to eouneet the brake rod with a bent rod l. U J. whieh latter passes at J. through the slots or broke eyes lt. in the pieees I'. 'lllt'lt are fastened to the frame work of the sleigh. are of iei'uliar form and serve as l'ulera f r the I'IX l. (l J.

.\ hand I. fastened around the tongue' The brake eyes This motion of the lll'lkl' rod pulls the upper part [4. ol' the rod l. ()J.

forward o as to raise the hooks or hrnkes Q. at the ends of "til I U J. nlmt'e the ,'..'t'nt|l| l and keep them In this posttionas long as the horses pull. This position at the t l l I lines. the fulcrum of the rod l. t) J. heing at the lower ends of the brake eyes 1:. R. 'hen the sleigh eonunenees to deseeud a grade sutfieiently steep to require the eheeking aetiou of the broke. the tendeney of the sleigh to deseend hv its own weight. pushes the front end of the tongue forward until it nhuts against. the front plate of the. ferrule A. The horses heing lllltllttl to the hook t. of the ferrule and holding ltitt'li while deseending the steep grade the ferrule and tongue will remain in the same position relative to liltll other until the sleigh has arrived at the hollow of the steep grade. when the horses eonunenee again to pull and thereby draw the ferrule forward us atready deserihed.

It will he seen that while the tongue mores forward in the ferrule at the eonnnem'enn-iit of the descent of the sleigh as above set forth. the relative aetion ot' the parts is the same as if the ferrule were pushed hark until its front plate ahuls against the front end of the tongue: the brake rod l).n1oring Inn-k together with the ferrule pushed haul: the upper part [1. of the rod l. t) J. the lower ends of the hralt'e eyes It. ll. serving as ful- ('t'tt. and the hrake hooks Q. are depressed so as to engage with the surt'aee of the road and eheek the tendeney of the sleigh to deseend h its own weight. This position ol' the brake is represented in Fi *2. h dotted hlaek lines.

\Yhenet'mthe horses are roused to hark the sleigh the urtinn ol the ferrule. ht'ake rod. and upper part of rod I t) .l. is lltt same as in the ease of dust-ending a grade as ahot'e set forth. hut as soon as the lu'ake hooks toueh the stlt'l'nee ot' the road. the strain on them eauses the parts .l. of the rod l. t) J. to slip hark and upward in the lu'nke eyes It. lt. until resting against the upper end of said hrake eyes as represented hr red lines in Fig. 2. when the hrake hooks will just slide over the slu't'aee of the road without engaging with it and aellng in the l'tllttlt'll v of a Make.

The slot ie of the hollow spare ot' the lil'ake are t. i illstinetly hown in Fig. it: it i'ullslsls of a horizontal slot I whieh ettt't'es llpwnt'il into a \ettieal slot '1. as

hralnis represented in Fig. :2. in l'nll lilaek l seen in said Fig. :5.
